The first thing you want to do is to sharpen your lawnmower blade. A dull blade
will tear the blades of grass rather than cutting them. This will make your lawn
more susceptible to disease and may cause it to turn a dull brown colour.
Your first mowing should be at a height of approximately 1.5 inches. In the following weeks, raise your mower one notch at a time until you reach a mowing height between 2.5 and 3 inches. This length helps shade your roots and provides more leaf surface for your lawn to manufacture its own food. The proper height also helps your lawn retain its moisture during the warmer Summer months. As a rule, never remove more than one-third of the leaf blade in a single cutting. Proper mowing will help maintain the health and appearance of your lawn, and will make it difficult for weeds to grow in.
